If you choose to look at the sun with your eyes (rather than by projecting the sun onto something else), then you must always have a solar filter between you and the eclipse. Use a solar filter on your viewing equipment. You can also use a pinhole camera for eclipse viewing.If it is a total eclipse, then it will turn into a thin-lined O. When the eclipse takes place, that circle will shrink and turn into a crescent, if it is a partial eclipse.You can bring it into sharper focus by moving the pinhole projector closer or further away from the ground.

The circle may appear fuzzy at the edges.

When the projector is properly aligned, you should see a perfect circle on the other piece of card you placed on the ground.

It should be held in the direction of the sun and you should be facing the screen you placed on the ground. Make sure your head is not covering up the hole.

Standing with your back to the sun, hold the card a few feet off the ground above your shoulder or to your side.

Place a second piece of paper on the ground to serve as the screen you will be projecting the eclipse onto.

Poke a small hole using a pin or thumbtack through the center of a piece of cardstock.

Its drawback is the very small image it produces, but this one is ideal for children and young teens who will enjoy the process of preparing the pinhole projector and then using it. A homemade eclipse viewer or pinhole viewer is very simply done and, generally speaking, it is the easiest and safest way to view an eclipse for just the price of some thick poster paper or cardstock.

Make an eclipse viewer or a pinhole projector.
